Abstract
A computer-implemented method for balancing data tape cartridge utilization in an automated tape library system identifies a current number of data tape cartridge mounts per library string and identifies a target number mounts per the library string to identify a difference between the target number and the current number as a delta number of data tape cartridges to move. The number of data tape cartridge mounts per data tape cartridge per library string is identified and a data tape cartridge to move is selected by identifying a unique identifier of the data tape cartridge with the highest number of mounts, and having a lowest number of moves, to form a selected data tape cartridge, and creates a move request for the selected data tape cartridge. The move request is sent to the automated tape library for execution, and a move counter for each data tape cartridge moved is incremented.
